Paper Valentine is about a girl named Hannah who is living through one of the hottest Julys on record. And her best friend Lillian died six months before from anorexia. Plus there is a serial killer, a.k.a. the Valentine Killer, on the loose in town. Last, but not least, Lillian is now haunting Hannah and bugging her to investigate the mysterious deaths of the girls who are the serial killer's victims. Creepy in a dead-best-friend-haunting-you-while-a-serial-killer's-on-the-loose kind of way.

The Dead and Buried is about Jade, whose family has just moved into a new house in a new town. Jade is happy about the new house and about the fresh start for her and her family. Unfortunately, the house is haunted by the ghost of a girl who died there and wants to know who killed her--and who doesn't care what she has to do to get the truth and to get her revenge.

Welcome Back to the blog for the next round in our Summer Reading series: Reading is Elemental. This week we will be looking at photosynthesis, an extremely important chemical reaction to all life on Earth.

Last week in our discussion on energy, we briefly mentioned that plants are able to convert the sun's energy into plant mass, now let's look at that process, called photosynthesis, in better detail.

Photosynthesis: a Chemical Reaction

The illustration above shows a simplification of what is happening in the natural world involving photosynthesis. We see that the energy from the sun's light (photons) creates a chemical reaction that combines (synthesizes) Carbon dioxide (CO2) and water (H20) to create some form of carbohydrate sugar (CH2O)n and leftover Oxygen (O2).

We list the equation out below, so that you can see the overall process. In our balanced reaction, we see that glucose (C6H12O6) is our representative of a carbohydrate. The important thing here is that the byproducts of this process are extremely important for life on Earth. We have to ingest carbohydrates and oxygen to have energy to live. When our bodies metabolize carbohydrates like glucose, we oxidize sugars to release energy for physiological movement (putting our bodies in motion). The byproduct of this process is CO2 which can then be stored again during photosynthesis.

For a more in depth look at the various types of chemical reactions, check out the Khan Academy video series.

Bringing It All Back Home

Again, what does this have to do with technology? Last time, we saw that when fossilized carbohydrates (hyrdocarbons--CnH(2n+2)) are burned, stored energy is released in the form of heat. That energy is converted into electricity that powers our electrical devices. The photosynthesis of hydrocarbons is the foundation for our electrical power.

For plants to continue to grow, they need balanced access to the key components of photosynthesis: water, sunlight, and Carbon dioxide (other elements like Nitrogen, Phosphorus and Potassium are crucial as well as you shall see later this summer). That balance is the basis of all gardening and agriculture. There are quite a few resources out there to help people find that balance and make their garden the most productive.

Congratulations to those who have begun the library’s Teen Summer Reading program! You are one step closer to completing the program and earning the snazzy messenger bag and other great prizes. Now, you may come to a time when you have either read all the books by one particular author or finished reading the entire popular series such as The Hunger Games or House of Night.

Where do you go to try something different? These two sites show you where you can find similar titles and authors of your interest:

With Fantastic Fiction, you can find where a particular title falls in a series, an entire bibliography of what the author has published, similar authors to a particular genre, and even upcoming titles soon to be released.

NoveList offers reviews and is able to filter books/authors similar to your taste. You can even narrow down what genre of literature you enjoy. Broaden your horizons by exploring these two websites.
